0.4.........4

4.00.........40

4 kilos = $40

1 kilo = $10 (40/4)

Answer 2

Option C. $10 per kilogram.

Explanation:

Amy bought 0.4 kilogram tomatoes for $4.00

Since the cost of 0.4 kg tomatoes = $4.00

Therefore, the cost of 1 kg tomatoes =
`(4.00)/(0.4)`

= $10.00

The cost of tomatoes is $10.00 per kilograms.
